The cyclic attribute “Config index“ has got a specific meaning.
Always when a configuration attribute changes and is transmitted to the client this index will be
incremented. Assuming the index‘ value is 60. If frequency configuration changes the index will be
incremented to 61 and when afterwards the name changes the index will be incremented to 62.
In case of a temporarily interrupt of UDP/IP connection it may happen that media control or any
other clients miss the reception of a configuration attribute that has been changed.
If the UDP/IP connection is established after an interrupt the client can compare the current ‚Config
index‘ value to the one the client received last. If there is a difference the client can request an
update of all configuration attributes.
The “Config index“ is limited to 999. Afterwards it starts from 0 again.
